    <p>You can access the object's properties via the <a href="http://msdn.microsoft.com/en-us/library/ms221608.aspx" rel="nofollow"><code>IDispatch</code></a> interface and its methods <a href="http://msdn.microsoft.com/en-us/library/ms221306.aspx" rel="nofollow"><code>GetIDsOfNames</code></a> and <a href="http://msdn.microsoft.com/en-us/library/ms221479.aspx" rel="nofollow"><code>Invoke</code></a>.</p> <p>Depending on your definition of <code>myMethod</code>, you should be receiving <code>obj</code> as either a <a href="http://msdn.microsoft.com/en-us/library/ms221627.aspx" rel="nofollow"><code>VARIANT</code></a> or an <code>IDispatch *</code> in your C++ code. If a <code>VARIANT</code>, <code>vt</code> should be <code>VT_DISPACTH</code>, in which case you can safely dereference <code>pdispval</code>.</p> <p>Once you have an <code>IDispatch</code> pointer, you can use <code>GetIDsOfNames</code> to get the <a href="http://msdn.microsoft.com/en-us/library/ms221242.aspx" rel="nofollow"><code>DISPID</code></a> for a property that you're interested in like so:</p> <pre><code>_bstr_t sPropertyName = L"myProperty"; DISPID dispid = 0; HRESULT hr = pDispatch-&gt;GetIDsOfNames(IID_NULL, &amp;sPropertyName, 1, LOCALE_SYSTEM_DEFAULT, &amp;dispid); if(SUCCEEDED(hr)) { ... </code></pre> <p>Once you have successfully received your <code>DISPID</code>, you must call <code>Invoke</code> differently according to whether you would like to get a value, set a value or call a method.</p> <p>For instance, to get a value:</p> <pre><code> VARIANT vValue; hr = pDispatch-&gt;Invoke(dispid, IID_NULL, LOCALE_SYSTEM_DEFAULT, DISPATCH_PROPERTYGET, 0, &amp;vValue, 0, 0); if(SUCCEEDED(hr)) { ... </code></pre> <p>See the documentation for <code>Invoke</code> for more information about the different permutations when calling it.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
